Environment is very similar to his brother R0, on which I worked a year ago, and thus the port will be quite straightforward.

So far, as per wiki, I have set up basic stuff to start with. LCD, Backlight, hardware buttons and basic support are working. Even audio playback works, but there is still missing the WM1808 codec support so volume is not controllable.
Moreover there is still no touchscreen.

I would kindly ask you, don't ask for betas or such. I don't want to spread nonfunctional/beta ROMs for the moment as I did for R0.
I will release the patch and git patch in ~2 weeks and I will release a beta when the basic ROM is cleaned and rockbox can be usable without problems (i.e. battery monitor + charging must work and also touchscreen is a must to release a beta)
